Description

Technical Field

[0001] This utility model relates to the field of rice seedling substrate mixing and homogenization technology, and in particular to a rice seedling substrate mixing and homogenization machine. Background Technology

[0002] Rice, as a major food crop in the world, occupies a core position in my country's grain production and is key to ensuring food security. Seedling cultivation is a crucial step in rice planting, and the quality of seedlings directly determines the yield and quality of rice. In the preparation of rice seedling substrate, it is necessary to fully mix and homogenize various raw materials such as soil, organic fertilizer, crop straw, and perlite to ensure that the substrate has balanced nutrients and good air permeability and water retention. As a result, rice seedling substrate mixing and homogenizing machines have emerged, which greatly improve the efficiency and quality of substrate preparation and lay a solid foundation for high-yield and high-quality rice.

[0003] When the rice seedling substrate mixing homogenizer is working, the high-performance motor drives the stirring shaft and its specially shaped blades to rotate at high speed. This causes the substrate raw materials, such as soil, straw powder, and perlite, to circulate axially and diffuse radially within the sealed container, achieving mixing. During the mixing process, strong shearing forces are generated between the blades and the materials and the container walls, breaking up clumps of organic fertilizer and large clods of soil into fine particles and dispersing agglomerates. At the same time, the strong vortex flow field generated by the high-speed rotation continuously impacts the materials. Under continuous stirring and impact, the substrate is deeply homogenized, ensuring that each batch of seedling substrate is mixed evenly and has stable and reliable quality.

[0004] While existing rice seedling substrate mixing and homogenizing machines have indeed played a positive role in promoting the mixing of rice seedling substrates across the industry, significantly improving the preparation efficiency and uniformity of seedling substrates, the equipment still has obvious technical shortcomings. Substrate raw materials such as straw powder and perlite are mostly added manually based on experience, lacking quantitative devices, which leads to deviations in material ratios and makes it difficult to stably control key indicators such as substrate permeability and water retention. To ensure mixing quality, producers often need to add other raw materials for slow-release adjustment, which not only increases costs but also prolongs the preparation cycle, limiting the standardization and refinement of seedling substrate production. Therefore, a rice seedling substrate mixing and homogenizing machine is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a rice seedling substrate mixing and homogenizing machine, which aims to improve the problem of material ratio deviation caused by the lack of quantitative feeding in the existing technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A rice seedling substrate mixing and homogenizing machine includes a base, a shell fixedly connected to the top of the base, a support frame fixedly connected to the outer wall of the shell, a feeding trough fixedly connected to the top of the support frame, a base fixedly connected to the inner wall of the support frame, a hydraulic cylinder fixedly connected to the inside of the base, a storage tank fixedly connected to the other end of the hydraulic cylinder, a feeding port slidably connected to the bottom of the storage tank, a hopper fixedly connected to the top of the shell, a motor fixedly connected to one side of the shell, and a cleaning and scraping assembly fixedly connected to the drive end of the motor.

[0008] As a further description of the above technical solution:

[0009] The cleaning assembly includes a rotating column, one side of which is fixedly connected to the drive end of the motor. Two connecting plates are fixedly connected to the outer wall of the rotating column. Limiting columns are slidably connected to the side of the two connecting plates away from the rotating column. Scrapers are fixedly connected to the other side of the two limiting columns.

[0010] As a further description of the above technical solution:

[0011] The bottom of the feed inlet is fixedly connected to the outer wall of the housing, and one side of the support frame is fixedly connected to one side of the base;

[0012] As a further description of the above technical solution:

[0013] Springs are fitted on the outer walls of both limiting columns, and multiple stirring rods are fixedly connected to the outer wall of the rotating column;

[0014] As a further description of the above technical solution:

[0015] One side of the spring is in contact with one side of the connecting plate, and the other side of the spring is in contact with one side of the scraper.

[0016] As a further description of the above technical solution:

[0017] A fixing plate is fixedly connected to the inner wall of the housing, and multiple cylinders are fixedly connected inside the fixing plate. A push plate is fixedly connected to the other side of the multiple cylinders.

[0018] As a further description of the above technical solution:

[0019] The outer wall of the rotating column is rotatably connected to the inner wall of the fixed plate, and the inner wall of the push plate is slidably connected to the outer wall of the rotating column.

[0020] As a further description of the above technical solution:

[0021] The base is provided with a material collection frame at the bottom, and the bottom of the shell is fixedly connected with a discharge port.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, by activating the hydraulic cylinder, the hydraulic system instantly generates strong power, pushing the storage bucket to slide smoothly along the guide rail on the base. During the sliding process, the circular through hole at the bottom aligns with the inlet. As the space between the through hole and the inlet of the storage bucket continuously increases, the raw materials in the full bucket form a pouring force under the action of gravity. They slide smoothly into the shell like flowing water along the channel formed by the through hole and the inlet. The whole process is completed in one go, laying a solid foundation for the subsequent efficient and uniform mixing process.

[0024] 2. In this utility model, when the motor switch is turned on, the motor output shaft drives the rotating column to rotate at high speed. With the stable connection of the connecting plate, the scraper and the rotating column maintain synchronous movement. During the rotation, the adaptive adjustment structure composed of the limiting column and the spring plays a key role. As the rotation speed of the rotating column increases and the centrifugal force increases, the scraper overcomes the spring resistance under the action of centrifugal force and extends outward along the direction of the limiting column. When the centrifugal force weakens, the spring pushes the scraper to retract inward. This process is repeated, and the scraper can closely fit the inner curved surface of the shell, completely scraping off the raw materials adhering to the inner wall during the mixing process, ensuring that the materials fully participate in the mixing process and significantly improving the utilization rate of raw materials.

A cleaning and scraping component is fixedly connected to the drive end of the motor 10.

[0033] Reference Figure 3 and Figure 4 The cleaning and scraping assembly includes a rotating column 14. One side of the rotating column 14 is fixedly connected to the drive end of the motor 10, so that the driving force of the motor 10 can be transmitted. Two connecting plates 16 are fixedly connected to the outer wall of the rotating column 14. Limiting columns 17 are slidably connected to the side of the two connecting plates 16 away from the rotating column 14. Scraper blades 19 are fixedly connected to the other side of the two limiting columns 17, so that the distance between the scraper blades 19 and the connecting plates 16 can be adjusted by external force.

[0034] Reference Figures 2 to 4The bottom of the feed inlet 9 is fixedly connected to the outer wall of the shell 2, allowing the raw material to enter the shell 2 smoothly. One side of the support frame 4 is fixedly connected to one side of the base 1, making the entire device more stable. Springs 18 are fitted on the outer walls of the two limiting columns 17. Multiple stirring rods 15 are fixedly connected to the outer wall of the rotating column 14, allowing the raw materials to be mixed. One side of the spring 18 is in contact with one side of the connecting plate 16, and the other side of the spring 18 is in contact with one side of the scraper 19, allowing the spring 18 to extend and retract when subjected to external force.

[0035] Working principle: The main raw materials of the seedling substrate are poured into the hopper 3, and the raw materials to be mixed in a fixed quantity are poured into the feed trough 5. When the raw materials in the storage tank 8 are full, the hydraulic cylinder 7 is activated, so that the storage tank 8 pours the full raw materials into the feed inlet 9 and enters the shell 2. The cylinder 12 is activated, so that the pusher 13 slides on the outer wall of the rotating column 14 and makes reciprocating motion, pushing the raw materials entering the shell 2 from the feed inlet 9 to the same position as the raw materials entering the shell 2 from the hopper 3. The motor 10 is activated, so that the rotating column 14 drives multiple stirring rods 15 to work, so that the raw materials are fully mixed. Due to the presence of the connecting plate 16, the scraper 19 moves synchronously with the rotating column 14. Due to the presence of the limiting column 17 and the spring 18, the scraper 19 can adjust the distance according to the centrifugal force generated by the rotation of the rotating column 14, so that the raw materials adhering to the inner wall during the mixing inside the shell 2 can be scraped off more fully, thereby improving the utilization rate of raw materials.
